Application and June 21, 1905. serial No. 266,364.

To all whom it may concern. k I Be" it known that we, JOHN A. CARLSON and WALTER H. SHIMPF, citizens of the county'of Denver an State ofOolorado, have invented certain new and useful Imrovements inOarbureters'; and We do here-a y declare the followin to be ,a"full, clear,-

and exact descripti n the invention, such as will enable others skilled inth'e. 'a'rtto which it appertains to make andl'use the same.

This invention relates to improvements in gasolene-en ines,:'and more particularly to a, I y

" standf-pipe .5. An adjustable pine is carried carburetertlerefor. a One of the objects of the invention is the provision of means for obtaining a more com-' .plete mixture of air and gas and to facilitate the regulation ofthe proportions of air and gas in the mixture.

Another object of the inventionis the im -o v g I y justing-the locking member 8 to'w'ardthe up-,

'per end. of the pinfisai'd pin may be ad'usted provement of the construction ofvalve means employed in the construction of a carbureter.

structions, combinations, and arrangements p of arts, as will be hereinafter fully descri ed, illustrated in the accompanying drawings, and more particularly pointed out in the claims hereto appended.

Our invention relates to improvements in a devicefor introducing gas and air in a mixed condition into the combustion-chamber of a gas-engine. The mechanical structure of our invention deals with a device employing a primary or outer casing, a valvecasing ositioned Within said primary casing, and va ve means movably mounted within said valve-casing.-

at Denver, in the.

The preferred structure of our invention is illustrated in the accompanying drawings, in

which- 1 designates the primary or outer casing,

which contains the valve means. Air is admittedinto the primarp or outer casing through opening or port .2: he 'rimary casing'l is provided with a pipe or ollow extension '3, through which themixture is passed into the combustionchamber of an'e'n ine.

A gasolene tan or reservoir 4 is formed upon the primary casing 1 andis connected by'suitable means to the removablegasolene by the casi '1. The in 6.is employed for regulating ialie flow' oi g'asolene from the standipe 5. The .pin 6 constitutes a neechamber and v dle-va ve, which is',-fixedly secured in any adjusted. position by. means of lever-locking member 8. "It will be obviousthat by'ad-i upon'the casing l for-re qating" the owof 1i uids through'thestan pipe 5'.

ositioned' thin a" dsupport'e'd upon the internal collar or depending portion 13 of the.

' rir'nary" or outer ca'smgl is a'valvejcasing or ining 7. The valve casing or linin -7 is artly closed at one end by means of averti= v 5 cal portion 7, which is prefelglbly integral with the auxiliary cas' o'r thimble 7*. he lining7. is provided wit an inlet, auxiliary air-port 9, and

auxiliary casing or thimble which are positioned the-stand-pipe or 'plug i and the P111 6, constituting a needle-valve,

Fi 2. v

The throttle-valve comprises a primary for receiving nut 20. The portions 17 of the primary member. 14 of the valve are prefer.- ably segmental in CI'OSSfSBOtIOD. fgr' accompreferably with outlet-ports. -10.- Inthe sma 7 there are formed apertures 79-, within:

e plunger 'or member 15.

parallel portions or arms 17, whichwith the stem- 18. The outer end of the stem '18 is threaded too modating the auxiliary member when positioned thereon, as depicted in Fig. 2.

The auxiliary member 15 of the valve is provided with outletorts 21, said member 15 being also provide with a hollow stem 22 and a vertical portion 22, which partly closes one end thereof. When in its normal position, the auxiliary member 15 is posi: tioned upon the .portions 17 of the primary member and is in engagement with the inner face of the stationary valve-casing 7, as clearly seen in Fig. 2. The hollow stem or sleeve fits over the stem or shank 18. "After the valve-casing 7 has been positioned within the primary casing 1 and the valve means positioned Within said valve-casin a locknut 23 is adjusted upon one end 0 the primary casing 1, Fig. 2, which entirely closes said end and holds the valve-casing and its valve, in position. A primary lever '25 is swivelecl upon the hollow stem or collar 22 of the primary member 15 and an auxiliar lever 19 carried by the stem or shank 18 0% the primarymember 14. By loosening the nut 20 the (primary member 14 canberotated indepen ently of the auxiliary member 15 but if it is desired to s chronously actuate the primary and aux iary members 14 and 15, respectively, the nut 20 is tightened against the auxiliary lever 19 and binds upon' the primary lever 25,- thereby firmly securing said levers 19 and against independent move- 1 chine.

ment. An aperture 26 is formed in the lever 25, (or any other ordinary means may be employed) by which the lever is connected with the gear operated by the driver of the I118:

It is toi be noted that the outlet of the stand ipe 5 is positioned within the assage 24 of t e casing 7 and that some of t e'air is drawn from chamber 1 1 through this passage 24 into the mixing-chamber inside of the valve, and as the air comes through the passage 24 it draws with it the gas from the openingxi ni1 the stand-pipe 5.

en the lever 25 is in itsnornial position,

Fig.3, it will be noted that the inlet-ports are to one side of a direct horizontallinewith the outletorts-that is to say, the side .10" of each 0 the Lorts 10 is not formed on the same i horizontal me with side 9 of theparts .9, I

Figz e. This is true-of the ports in the valve, 'aswell as in the casing. The objects of thispn;- sitioning of the ports in the valve and casing' is to force the air which comes in through the inlet-ports to move in a more or less spiral f direction before reaching the outletports, thus makin the mixture within the chamber more-comp etc. By turning lever 25=to the proper position both i'nletand outlet ports Willbe closed, butan eighth-turn will throw both wide open. Then the valve is in the position shown in Fig. 2. When it is desired tothen turned slightly to the loft and the nut 20 is then fastened tightly against said lever. The fastening of this nut binds the parts of the valve firmly together, so that all parts will turn together with the adjustment of the lever 25. It willthen be seen that a sufficient turn of the lever 25 to throw the inlet-ports 9 let-ports, and the result will be-that the-suc- .tion at the outlet-ports will be less for the reason that the outlet-ports are made similar; but while the outlet is less the amount of airpassing through the inlet-ports will be the through the passage 24, which in turn will resultin a drawing of a less quantity of gas. If the reverse of this is desired, locking-nut 20 is loosened,-lever 19 is turned to the right, thus throwing the outlet and inlet orts of the valvenearer upon-a line. The ockin'gnut 20 is again fastened firmly against lever 19, and with the valve in this position a turn of the lever 25 will only open the outlet-ports, while leaving the inlet-ports not fully open. This will increase the suction through passage 24 of the auxiliary casing7 and draw more gas in proportion to the air. noted that the ports in' the valvecasing, as well asmembers 14 and-15, arenot rectangular, but in each instance are provided with a side 10, which is formed at an angle to the longitudinal plane in, which the other side is formed. This idea of the slanted sides of the ports makes it possible to obtain a more gradthe casei the orts or openings were provided with para el sides.

1 'It is to be noted that the primary or outer casing is preferably cylindrical in shape and isconstructed ofsections, each section being provided with a flange 1. The flanges 1 abut and are firmly secured together by suitable fastening meansas, for instance,

screws 1", Fig. .1. The reservoir 1 is pro- 3 vided with a removable top ,4, fixedly secured in position by suitable removable fastening means, as screws 4. The tubing 4is the .main, supplyipe, and connection is made with the stan {pipe through drilled apertures in the body'of the reservoir. In the foregoing description we have de:
